My 505 motor makes 800+ hp with CNC ported EZ heads and a .700 lift roller cam. It does have 13.5 compression so that would have to be backed off for a pump gas motor. The point is, you don't need to go crazy with the heads to run 9's.

Sit down with the Mopar chassis book and figure out how much power you need to run 9's at your weight and what gear ratio you need to run the speed. Then sort out the engine combo from there.

Remember, NHRA guys can get 318's with QJet carbs to run 9's with factory cast iron heads.

My max wedge victor headed 505 made 770 hp with bracket porting, mild .700 lift roller and 13.1.
EASY nines in an abody.

I wanna stay on pump gas though... my chally (3800lbs)went 10.6/128.3 and @ 13.8 WOT on the wideband its first and only time out with mch indy cnc ez's basically the cnc 295 version with a small 248/254 solid roller .640 net lift.... Im sure it would have went quicker with some tuning... that was on dot's / pump gas and throught the muffs... wonder how much difference the 325 indy ez's witha bigger solid roller would make in a 300lb atleast lighter car I have a brand new custom comp roller made I never got to use and its 260/266 @ 50 and about .650 net lift with 1.7's

personally, if i had a 572 this or a 588 that, and it only ran high 9's i would be too embarrassed to tell anyone. but that is just me.

If I had a gutted, lexan windowed, big tire, backhalved all out race car that only ran 5.90s to 6.0s in the 1/8 then I'd be embarrassed...but that's just me.

There's a big difference in building a PUMP GAS combo for a HEAVY car than a lightweight high compression combo. CHIP

everyone thinks its so easy to go 9's in a heavy car that runs pump gas.
my 581 Hemi just barely goes in the 9's in bad air and thats pump gas with a .737 cam. 3500lbs.

[ Whats wrong with 10.teens and getting sent home on the occasional perfect air day when you grab that 9 second slip.
NHRA just raised all thier fees, that means more to cert the cage, higher membership, licsense, competition number. Physical every two years, 3 layer jacket and pants, neck collar, gloves, engine diaper, flexplate shield...all that so you can run 9.8 the three times a year you get it to a track.

---

i agree 100 %

that is why i am perfectly happy with my 10 teens
even though i am told there is a lot more left in my combo .

by the way i use the OTB victors and they were not that big of a deal to use . a little clearancing for push rods and some different intake rockers ($240 from hughes)

believe me chip when i say i surely wasn't thinking about you when i said that. but, the truth is you have more money in your motor than this whole car has in it. this thing just has e-heads and a flat tappet cam. i do believe that "5.90 to 6.0" equates to more than 9,90"s

Getting back to the original question....Prosport ran 9.90's with his Dart with what I believe was an Eddy RPM headed 451....So if Wedgie is planning on 540 inches I would say -1's would put him solidly where he wants to be.

Lets hope so....

I do have a lot of money in this motor and you're right, it most likely cost more than your whole car, but it does EXACTLY what I intended it to do. Not to mention it's built with some of the best parts you can buy (Callies, Oliver, Diamond, KB, etc.). I can beat on this thing mercilessly, I've done so for the past 3 years, and never have an issue with it. It can handle a lot more than the 825 or so horsepower it's currently making without fear of the bottom end not being up to the task. You could build it much cheaper, but I built it to last, be streetable, and have room to grow when I decide to go faster. Excuse me for having the budget to do that.

It's all in what YOU want. Myself and Wedgie like fast small tire STREET cars that still resemble what left the factory, can fill up with fuel at any corner gas station, and can be driven to the beach for a weekend. Comparing the motor from one of our cars to yours is apples to oranges. In a heavy car that requires pump gas, you need to offset compression and camshaft with cubic inches.

And yes, 5.90s to 6.0's is faster than 9.90's. Mine goes 6.0's in good air running 9.50's. More gear for the 1/8 and it should go into the 5.90's, but I don't want more than the current 4.10s on the street. CHIP
